I'll be honest. The money I have in the roller valve train and as hard as I spin it, it scares the crap out of me. When I first put it on alcohol this summer, I was a mess when I fired the car up. All of a sudden the car was quieter and I could hear noises in the valvetrain that on gas I couldn't. Now when I lean the fuel out, it goes right back to its snotting self.
